While you may be using exim4 on the same machine as your email client, this isn't the expected usage, and MITM attacks may happen in a network (or even within a computer, for that matter). Email clients do this sort of thing routinely (the mis-spelling is not mine, that really is the page name): https://securityinabox.org/en/thuderbird_encryption Some people may use multiple email clients on different computers, with the mail all sent out through a network server, as I do. It would be convenient to do all the configuration in one place, but less secure, and not many people work in this way. About the only ready-made single-point-configuration solution will probably be webmail based on the server. Squirrelmail can use GPG though I don't know how sophisticated it is. -- Joe -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
